# Use the Chilkat Email API to create or load an email.
$email = New-Object Chilkat.Email
$email.Subject = "This is a test GMail email created using Chilkat."
$email.Charset = "utf-8"
$email.AddPlainTextAlternativeBody("This is a test")

$sbMime.Encode("base64url","utf-8")

# The body of the HTTP request will be JSON..
